SPECIFICATION forming part of Letters Patent No. 641,445, dated January16, 1900. Application filed January 20, 1899..v Serial No. 702,817. (Nomodel.)

T0 @ZZ whom, it' may concern.-

Beit known that we, ALBERT M. FERGUSON and KENDRICK P. SHEDD, citizensof the United States, residing at Rochester, in the county of Monroe andState of New York, have invented new and useful Improvements inBicycle-Vheel Tires, of which the following is a specification.

This invention relates to improvements in pneu matic tires, such as areused for bicycle and other wheels; and it consists in providing samewith a non-puncturable annular shield, the said shield consisting of aseries of concave-convex metallic plates, an inner and an outer annularelastic cover of greater width than the plates, and rivets whereby eachplate is centrally secured to the two covers. Y

The invention further consists in certain details of construction, ashereinafter fully described and speciiically claimed.

Our improvements are clearly shown in the accompanying drawings,whereon- Figure l is a perspective view of a section of a pneumatic tireprovided with our improvement. Fig. 2 represents an inside View of ourimproved shield, parts of the inner annular cover being broken away inorder to show the interjacent concavo-convex plates. Fig. 3 is an endview of one of the said plates, and Fig. 4 is a side view of same.

Referring to the drawings, the letter at designates the inflatable innertube, and b a section of the non-puncturable shield or protectorthereof. The said shield is composed of a series of concavo-convex steelplates c, which are arranged to lap one another and which are thus heldby being riveted to inner and outer annular strips of rubber or otherelastic material, as indicated at d e. The

whole is inclosed within an annular rubber or elastic shoe f, the treadof which is preferably provided with raised ribs h h', arranged inparallel or diagonal lines, so as to insure a better hold on the surfaceover which the wheel is propelled. This shoe is designed to be laced atits back or inner side and to rest in the ordinary concave rim of thewheel.

From the foregoing description it will be seen that the construction ofour shield is 5o such that it not only protects the tire from puncture,but saves the shoe or outer covering and the tire from being cut orotherwise injured by the scales or concave convex plates of which theshield is partly composed. 5 5

The resiliency of the wheel is in no way impaired by our shield,inasmuch as the said shield has no direct connection either with thetire or shoe.

Having described our invention, what we 6o claim as new, and desire tosecure by Letters Patent, is

1. As a new article of manufacture, a shield for pneumatic tires, saidshield comprising a series of overlapping concavo-convex metal plates,an inner and an outer elastic cover of greater width than the plates andrivets whereby each plate is centrally secured between the two elasticcovers, as and for the purpose described.

2. In combination with a pneumatic tire,

a shield composed of a series of overlapping concavo-convex plates, aninner and an outer elastic cover of greater width than the plates,rivets whereby the plates and covers are secured together, as described,and a shoe, or outer cover of elastic material, substantially as setforth.

In testimony whereof we have hereunto set our hands this 2d day ofAugust, A. D. 1898. 8o
